description The invention relates to a digital self-correction method and system for frequency in an oscillator and a storage medium, and belongs to the technical field of oscillator frequency correction. Through regulation and control of an analog comparator, real-time voltage information is input into the analog comparator, a comparison result is obtained, a plurality of regulation and control schemes are preset, and the frequency in the oscillator is corrected. And adjusting the frequency information through a counter based on the regulation and control scheme and a comparison result. By fully considering the mismatch of the analog comparator, a simple control design can be used, an automatic frequency detection and correction method is provided, the frequency drift of the oscillator is reduced when the temperature and the voltage change, the high-precision oscillator is provided, and the identification precision of the frequency is improved. By converting frequency information into voltage information, automatic freq
